SLB-10B-70P 10.0 mm Dia. x 70.4 mm FL; Double-Convex Lens Uncoated

The SLB-10B-70P is a high-quality double-convex lens offered by OptoSigma, a leading vendor in the optical industry. This lens, with a diameter of 10.0 mm and a focal length of 70.4 mm, is designed for use in a wide range of optical applications.

The lens is made from n-bk7 schott, a popular optical glass due to its excellent optical properties. The base shape of the lens is circular, and it features a spherical geometry, with a center thickness of 2.3 mm and an edge thickness of 2 mm. The effective focal length (EFL) of the lens is 70.4 mm, and the back focal length (BFL) is 69.6 mm. The radii of curvature for the first and second surfaces are 72.66 mm and -72.66 mm, respectively.

The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means that the lens is more versatile and can be used in a wider range of wavelengths. The lens is designed to operate at a wavelength of 546.1 nm.
